SKEIN HOLDER FOR THREAD-SPOOLING MACHINES.

.Ap'plication filed December 18, 1926, Serial No. 155,715, and in Switzerland June 26, 1926.

Reeling and winding machines are known wherein a plurality of reels or the like are mounted between the arms of spider frames whereby they can be brought successively 6 into and out of operative position, the object being to enable one reel to be prepared while another one is in operation.

The present invention relates to a deviceof this kind for use as a skein holder for thread spooling machines, and the invention consists essentially in mounting the spider frames by means of hubs on a shaft having longitudinal, equidistant grooves, the hubs being provided with spring-pressed balls adapted to engage in said grooves for retaining the frames with different reels in operative position.

The frames are moreover provided for each reel with a known form of thread tensioning device composed of a U-frame arranged so as to swing about the axis of a reel, the frame being according to the invention fitted with a thread guide and with an adjustable weight whereby the tension can be regulated.

Fig. l of the accompanying drawings represents a side view of an arrangement according'to the invention,

Fig. 3, a .rear View of the arrangement,

Fig. 4, a side and a top view of the spider frame, and

Fig. 5, a view of a thread guide employed in the arrangement.

, A supporting frame 1 carries rigidly a horizontal shaft 2 on which one or more reel holders are arranged so that they can be adjusted thereon longitudinally and rotatively. In the construction shown, each reel holder is composed of a hub 6 to which three pairs of radial, equidistant arms 11, 12'and 13 are connected so as to form a spider frame. Between the free ends of each pair of arms, at 14:, 15 and 16 respectively, a reel is mounted so that it canbe turned by means of the holder into and out of operative position. Fig. 1 shows one reel 19 in operative position over the spooling device 25, while two machine where they can be fitted up with skeins or hanks so as to be ready for the spooling operation as soon as the reel 19 is empty. 2

To secure the holderv with either reel in operative position, the shaftv 2 is provided reels 1'? and 18 are held at the back of the with three equidistant, preferably semi-cylindrical, longitudinal grooves 3, 4 and 5 carried through the whole length of the shaft. The; hub has a drilled stub in which there is a ball 8 a spring 9, and behind the latter an adjusting screw 10. The spring bears against the ball and causes it to snap into the grooves of the shaft for retaining the reel holder in its different positions. The screw 10 is adjustable so that the spring pressure, while suflicient for retaining the holder, allows thelatter to be turned from one position to the other. The holder or holders can also be moved to any suitable position along the shaft;

For maintaining the thread 24 in uniform tension on its travel from the reel to the spool 25, a U-frame 21 is hinged at 20 to each pair of arms. A thread guide in the form of a rod 23 is arranged along the transverse member of the frame 21 and connected thereto at one end only so that the thread can be easily slipped in between the rod and the frame member. The frame 21 tends to hang perpendicularly from the suspending point and is deflected more or less from this position by the thread 24 which will therefore be kept'in regular tension. To regulate the tension, a weight 22 is arranged on one of the radial frame members so that it can be adjusted thereon according to requirements.

The frame 1 may either form part of the spooling machine or constitute a separate structure.

I claim:

1. A skein holder for thread spooling machines comprising a horizontal shaft having equidistant longitudinal grooves, a support to which said shaft is rigidly connected,

hingedly to theends of each pair of arms,

a thread guide at the free end of said U- frame, and a weight arranged adjustably on said U-frame.
